Nevada has become the fifth state to legalize the sale of recreational marijuana, but a battle with state liquor distributors could cause some stores to run out of pot. The new marijuana law, implemented on Saturday, contains a requirement that only Nevada's alcohol distributors can legally transport the product from cultivators to stores, known as dispensaries. The problem is, none of the liquor companies have been licensed by the state to do it. "I think they'd like to do it; they're just not ready," said Andrew Jolley, CEO of The Source, a company with dispensaries in Las Vegas and its suburb Henderson. "We hope we have sufficient supply to last a few days or weeks until the distributors are able to come online to supply us." That's the big "if."
